Bishop Robert Caldwell (1814–1891) was an Evangelist missionary and linguist, who academically established the Dravidian family of languages. He served as Assistant Bishop of Tirunelveli from 1877. He was described in The Hindu as a 'pioneering champion of the downtrodden' and an 'avant-garde social reformer'. The Government of Tamil Nadu honoured his 'historic contribution to Tamil' with a memorial and issued a stamp in his name.  On the Madras Marina, a statue of Caldwell was erected as a gift of the Church of South India in 1967.
Robert Caldwell was born at Clady, Northern Ireland, on 7 May 1814 to Scottish parents. Initially self-taught and religious, young Caldwell graduated from the University of Glasgow and was fascinated by the comparative study of languages. At 24, Caldwell arrived in Madras on 8 January 1838 as a Presbyterian missionary of the London Missionary Society and later joined the Society for the Propagation of the Gospel Mission (SPG). To further his missionary objectives, Caldwell realised that he had to be proficient in Tamil to proselytise the masses and he began a systematic study of the language. He was consecrated Bishop of Tirunelveli in 1877. In 1844, Caldwell married Eliza Mault (1822–99); the couple was to have seven children together. She was the younger daughter of the veteran Travancore missionary, Reverend Charles Mault (1791–1858) of the London Missionary Society. For more than forty years, Eliza worked in Nagercoil and Tirunelveli proselytising the vulnerable, especially Tamil-speaking women.
The Dravidian languages
Robert Caldwell used the term Dravidian to separate languages prevalent in South India from other, more Sanskrit-affiliated languages of India. Apart from the main South Indian languages of Tamil, Telugu, Kannada, Malayalam, Tulu, Brahui in Afghanistan is considered to belong to the Dravidian language family. A few more languages have been identified as such. Scholars in the 19th century prior to Caldwell considered Tamil and other South Indian languages to be rooted in Sanskrit and affiliated to the Indo-European language family. Many linguists have accepted and confirmed Caldwell's work but critics such as Charles E. Gover, author of The Folk Songs of South India, have disagreed with his findings.
While serving as Bishop of Tirunelveli (alongside Edward Sargent), Caldwell did much original research on the history of Tirunelveli. He studied palm leaf manuscripts and Sangam literature in his search, and made several excavations, finding the foundations of ancient buildings, sepulchral urns and coins with the fish emblem of the Pandyan Kingdom. This work resulted in his book A Political and General History of the District of Tinnevely (1881), published by the Government of the Madras Presidency.
This book has been described as being on occasion "... pejorative, outrageous, and somewhat paternalistic. But on the whole his studies represent a pioneering effort to understand religions completely foreign to the British mind". It remains a respected work today.
Caldwell’s mission lasted more than fifty years. The publication of his research into both the languages and the history of the region, coupled with his position in both Indian and English society, gave stimulus to the radicalisation of the Non-Brahmin movement.
Meanwhile, on difficult ground for evangelism, Caldwell achieved Christian conversion among the lower castes. He had adopted some of the methods of the Lutheran missionaries of earlier times, having learned German purely in order to study their practices. According to the Church of South India, the "SPG stronghold, idaiyangudi Idaiyangudi ... was ... entirely a product of the labours of Dr. Caldwell. ... With such devotion and wisdom did Rev. Caldwell apply himself to his task that his rewards were phenomenal. Entire villages accepted Christ, churches and schools sprouted up so fast that Idayangudi soon became a model Christian settlement."
In summary, Caldwell the Tamil language scholar, Christian evangelist and champion of the native church, remains today an important figure in the modern history of South India. He is still remembered there, and his statue, erected eighty years after his death, stands near the Marina Beach at Chennai. The Indian historian Dr M.S.S. Pandian, Visiting Fellow at the Centre for the Study of Developing Societies in Delhi, recently commented that Caldwell’s "contribution to both Christianity in South India and the cultural awakening of the region is unmatched during the last two hundred years". 
A commemorative postage stamp on him was issued on 07-May-2010.
